Title Benzene exposure among mechanics - Atmospheric and biological monitoring
Original title Exposition au benzène chez les mécaniciens - Evaluation atmosphérique et surveillance biologique [in French]

Abstract This study on the evaluation of benzene exposure was carried out among 114 vehicle mechanics working in 37 garages. On each evening during a week of work, workers were questioned on the tasks they performed during the day. Daily samples of personal workplace air and urine were collected, the latter for the purposes of determining muconic acid excretion, which is an indicator of all modes of benzene exposure. Results indicate that the exposure to atmospheric benzene is moderate, but more pronounced among mechanics working in garages for motorcycles or agricultural equipment (0.14 and 0.16ppm respectively) than among those working in automobile garages (0.03ppm). Atmospheric concentrations were in agreement with urinary concentrations of muconic acid, which were 0.21, 0.27 and 0.09mg/L among mechanics at garages for motorcycles, agricultural equipment and automobiles, respectively. It is concluded that preventive measures should focus mainly on mechanics in motorcycle and agricultural equipment garages.
